Further to what Jim says, a year into office, the Trump Administration still gives off an extraordinary sense of brittleness. Just when it seemed Gen. Kelly had things on a more solid footing, the Rob Porter scandal has dragged the White House back to the old days of real-time, clashing leaks. Maybe it blows over in another day or two — the way almost everything does — but the fall-out could endanger Kelly and/or Don McGahn’s standing with Trump. And those two, especially Kelly, don’t seem easily replaceable. Meanwhile, Rachel Brand is leaving a plum Justice department job, perhaps out of reputational risk, or fear that she’d be left holding the bag in a Saturday Night Massacre-type event, or frustration that many Senate-confirmed positions under her hadn’t been filled. How easy will it be fill her own position now?
